GEORGE FLETCHER, OF HUME, ASSIGNOR OF ONE-HALF HIS RIGHT TO JASON S.BISHOP, OF FILLMORE, NEW YORK.

I MPROVEMENT IN PlPE-WRENCHES.

Specification forming part of Letters Patent No. [91,666, dated June 5,1877 application filed May 19, 1877.

To all whom it may concern Be it known that I, GEORGE FLETCHER, of Hume,in the county ,of Allegany and State of- New York, have invented a newand valuable Improvement in Pipe-Wrenches; and I do hereby declare thatthe following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a perspective view of mypipe-wrench.

The nature of my invention consists in the construction and arrangementof g a pipewrench, as will be hereinafter more fully set forth. a

The annexed drawing, to which reference is made, fully illustrates myinvention.

A represents the handle or lever of my pipe-wrench, provided on the endwith a head,

B. This head is somewhat in spear-shape,

with two convex faces, a a, both of which are serrated or toothedtransversely, as shown.

On the neck of this double head B is pivoted a metal frame, (J, whichstraddles the head, and has its ends curved to form the jaws D D. Thesejaws are curved to form arcs of circles of different diameter, makingone jaw larger than the other, and the frame 0, of which said jaws formapart, is pivoted to one side of the center, so that the larger jaw willhave the longest distance to the pivot, as shown in the drawing.

By this construction of the parts the wrench is adapted to pipes ofdifferent sizes, and, when adjusted to a pipe, will take a firm andsecure hold on the same.

The open frame 0, curved on arcs of circles at its ends, with thecross-bars at the ends forming the jaws D D, as described, straddles thehead and neck thereof, and does not necessitate any slot or mortise,which would be apt to weaken the wrench. It is easily made, and formsstrong and durable jaws to act in conjunction with the double head B.

What I claim as new, and desire to secure by Letters Patent, is

In a pipe-wrench, the combination, with the lever or handle A, of thedouble head B, having transverse teeth or serrations on both its faces aa, and the open frame 0, straddling the head, pivoted to one side of itscenter, and having its ends curved to form the jaws D D upon arcs ofcircles of unequal diameter, substantially as andfor the purposes hereinset forth.

In testimony that I claim the above 1 have hereunto subscribed my namein the presence of two witnesses.

GEORGE FLETCHER.

Witnesses: O. E. INGHAM, A. A. YAGER.
